{"id":"CVE-2022-23570","aliases":["BIT-tensorflow-2022-23570","GHSA-9p77-mmrw-69c7","PYSEC-2022-134","PYSEC-2022-79","PYSEC-2026-3153"],"url":"https://o3.security/vulnerability/CVE-2022-23570","summary":"Null-dereference in Tensorflow","details":"### Impact\nWhen decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is [guarded by a `DCHECK`](https://github.com/tensorflow/tensorflow/blob/a1320ec1eac186da1d03f033109191f715b2b130/tensorflow/core/framework/full_type_util.cc#L104-L106):\n\n```cc\n  const auto* attr = attrs.Find(arg->s()); \n  DCHECK(attr != nullptr);\n  if (attr->value_case() == AttrValue::kList) {\n    // ...\n  }\n```\nHowever, `DCHECK` is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the dereferencing of the null pointer, whereas in the second case it results in a crash due to the assertion failure.\n\n### Patches\nWe have patched the issue in GitHub commit [8a513cec4bec15961fbfdedcaa5376522980455c](https://github.com/tensorflow/tensorflow/commit/8a513cec4bec15961fbfdedcaa5376522980455c).\n\nThe fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.","published":"2022-02-04T22:32:42Z","modified":"2026-08-12T13:00:14.856569Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00992,"percentile":0.59415,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.5.3"},{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.6.3"},{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.7.1"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.5.3"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.6.3"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.7.1"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.5.3"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.6.3"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.7.1"}],"fix":{"url":"https://github.com/tensorflow/tensorflow/commit/8a513cec4bec15961fbfdedcaa5376522980455c","label":"tensorflow/tensorflow@8a513ce"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/a1320ec1eac186da1d03f033109191f715b2b130/tensorflow/core/framework/full_type_util.cc#L104-L106"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23570.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9p77-mmrw-69c7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23570"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/8a513cec4bec15961fbfdedcaa5376522980455c"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/tensorflow-cpu/PYSEC-2022-79.yaml"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/tensorflow-gpu/PYSEC-2022-134.yaml"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:00:14.856569Z"}}
